The APC PRO series brings a new level of performance and adaptability to the APC platform. All models feature a dual auto-folding, non-reciprocating charging handle, improved lower receiver ergonomics including a side positioned bolt hold open/release, removable M4 compatible grips, and Magpul® M-Lok® accessory slots.
Specifically the APC9 PRO SD, the SchallDämpfer version, is the integrally suppressed version of the APC9 PRO. From the Chamber back, it is identical to the APC 9 PRO. However, the barrel is ported to slow down supersonic ammunition, and the handguard is extended a bit to "shroud" the included suppressor.
